STRUCT MEI_CL_VTAG(9)

💅 struct mei_cl_vtag(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for struct mei_cl_vtag, which is literally the file pointer to vtag mapping structure. yes, that's the whole NAME vibe. it's giving "small struct, big responsibilities" ✨

🌸 SYNOPSIS 🌸

struct mei_cl_vtag {
    struct list_head list;
    const struct file *fp;
    u8 vtag;
    u8 pending_read:1;
 };

that's it, that's the whole struct. four members. no cap. look at that bitfield though — one single bit for pending_read, she's ✨frugal✨ 💅

🎀 Members 🎀

• list — her link in the map queue, i.e. how she gets chained up with all her little struct friends 🦋
• fp — the file pointer. literally the whole point of her existence 🫶
• vtag — the corresponding vtag. matching vibes only 💖
• pending_read — a u8 bitfield of width 1 that says whether the read is pending on this file. she's just sitting there waiting, main character energy tbh 😭
